I was prescribed Ritalin approx. 5 months ago for lack of motivation and feeling tired all the time caused by chronic low grade depression and or fibromyalgia I had for the last 15 to 20 years. Also taking Cymbalta which I am now weaning off of as it has lost its effectiveness 120mg for 3 years. Ritalin dosage was 20mgSR but dosage was increased to 40mg SR because after taking first 20mg lost its effectiveness after 2 hours. Have been taking 40 mg SR for the last few months! Can someone please let me know if headaches are the norm side effect from taking Ritalin , never had headaches before starting Ritalin.

Tks so much!
